Hi,
Thanks for your reply. Actually the prob was related to anti virus running on my machine. I have to disable it, But still it did not run and i got following authentication message:

However there was an important hind which i have highlighted above:
So i logged in and found an email in my account with subject:
Review blocked sign-in attempt
after that , i have to give permission to Less secure app.
However it did not run even after that because i was sending email to my yahoo account. So i send email to my gmail account and it worked. Then i tried sending email to my yahoo account and it worked too. Final output is:

enabling the debug mode on the mail session may help you.
...

I want to send email using gmail SMTP. I got the following code from internet but I am getting following run-time error.Kindly guide:<Exception in thread "main" java.lang.RuntimeException: javax.mail.NoSuchProviderException: smtp . . .at SendMailTLS2.main(SendMailTLS2.java:41)>
Well YOU are the ONLY one that knows what line in your code is line 41. As you can see above that is the line that caused the exception.
And this in your code says you really do NOT care what exceptions get raised or what causes them.
} catch (MessagingException e) {throw new RuntimeException(e);}Why do you 'catch' an exception and then totally hide what it is telling you?
Don't catch exceptions unless you plan to handle them. Adding that code just hides the REAL exception info you were given.
Remove that junk from your code and don't put it back.
Then rerun the code and SHOW US:
1. WHAT you do
2. HOW you do it
3. WHAT results you get
That includes posting a copy of the execution that includes the FULL exception and message you get.
But a missing provider message likely means you are missing a jar file that is needed.

}I ran it using the windows command line - just to make sure the IDE does not add anything to the classpath.

Hi,
Thanks everybody for kindly concentrating on my problem. God bless you people.
I have done the following as requested:
- Remove that junk from your code and don't put it back.
Yes
- But a missing provider message likely means you are missing a jar file that is needed.
I have provided the value of CLASSPATH by displaying the variable
- That includes posting a copy of the execution that includes the FULL exception and message you get.
Yes I have posted the full message
session.setDebug(true);
Yes I did this
- Well YOU are the ONLY one that knows what line in your code is line 41. As you can see above that is the line that caused the exception.
I have put the line numbers in the code.

java.lang.ClassNotFoundException: com.sun.mail.smtp.SMTPTransport
Your classpath does not have com.sun.mail.smtp.SMTPTransport class available to load hence the java.lang.ClassNotFoundException.
Edit:
First, download the mail-1.4.7.jar from https://mvnrepository.com/artifact/javax.mail/mail/1.4.7 and add to your classpath.
Then if you need, download smtp.jar from https://mvnrepository.com/artifact/com.sun.mail/smtp/1.4.5
I think you will also need further libraries - activation.jar.

First, change your code to look like ...
Transport tr = session.getTransport("smtps"); tr.send(message);and test.

I was able to connect using your code with just the changes in reply #8.
Transport tr = session.getTransport("smtps"); tr.send(message);output:

However there was an important hind which i have highlighted above:
So i logged in and found an email in my account with subject:
Review blocked sign-in attempt
after that , i have to give permission to Less secure app.
However it did not run even after that because i was sending email to my yahoo account. So i send email to my gmail account and it worked. Then i tried sending email to my yahoo account and it worked too. Final output is:
